The act of placing your hand under a girl's panties and then purposely avoiding direct contact with her vagina. Hand may be cupped. Typically used by virgins scared to move forward. Although intended to cause arousal, actual result is the girl wondering just what you think you're doing.

Yeah man, I was rounding third and headed for home when I decided to stop and just hover for a bit. Awwww, yeah, I got skillz.

To pace about restlessly and hang around impatiently while waiting for someone to complete a task for you, often accompanied by repeatedly looking over the person's shoulder. Erroneously thought of by the waiter as helping to speed things up, hovering generally has the exact opposite effect, causing the laborer to feel harried and nervous at being constantly watched, and thus actually making him take even longer to complete the task because his uneasiness obliges him to work more carefully and deliberately, and to re-check more details of his work than he would if he was calm.
Can also loosely refer to any form of fretting at or badgering someone, such as by phoning or e-mailing/IM-ing him repeatedly.

Husband: Is the shop almost done fixing our car yet?
Wife: Well, possibly, but I am not sure... they were still working on it when I stepped in, but they all appeared to be a bit stressed, so I didn't want to hover.

The act of taking a creepy, hauntingly ghost-like picture picture behind someone who is us unaware they're being photographed. Kind of like Planking, Owling and Horsemaning but with an unknowing accomplice.

I realized the girl had no clue about her surroundings so I decided to Hover and capture the moment.
